A pot experiment was conducted to study the influences of four phosphorus fertilizers（dipotassium hydrogen phosphate K2HPO4,calcium superphosphate SSP,calciummagnesium phosphate CaMgP and ground phosphate rock PR)on growth,cadmium and phosphorus accumulation of Amaranshus mangostanus L.in two acid soils including yellow brown soil and lateritic red soil.The results showed that phosphate treatments significantly promoted growth of Amaranshus mangostanus L.,reduced the Cd concentrations in Amaranshus mangostanus L.shoots and roots.And compared with other phosphorus treatments,the calciummagnesium phosphate treatment exhibited the greatest decline of degree that content of Cd in Amaranshus mangostanus L.shoots,with 58.4% and 77.7%,respectively.The accumulation of phosphorus and cadmium increased with the different phosphate fertilizers application in the two acid soils.In the yellow brown soil,the calcium superphosphate treatment exhibited the greatest increase of the accumulation of cadmium in the shoot,while the calciummagnesium treatment in the root.In the lateritic red soil,the dipotassium hydrogen phosphate treatment exhibited the greatest increased of the accumulation of cadmium in the shoot,while the calciummagnesium treatment in the root.The results showed that the capability of Amaranshus mangostanus L.accumulating phosphorus and cadmium was different when applying different phosphorus fertilizers in two acid soils.In the yellow brown soil,the accumulation of Cd by the Amaranshus mangostanus L.was better than other treatments when calcium superphosphate was supplied;In lateritic red soil,the accumulation of Cd in the Amaranshus mangostanus L.was better than other treatments when dipotassium hydrogen phosphate was supplied.
